INTRODUCTION
The Dunham-Bush Commitment...
The introduction of this new ACDS-B Scroll Air Cooled Packaged
Chiller line is further evidence of our commitment to continuous product
improvement and quality enhancement of our offering of quality products for the
HVAC and Industrial Markets.
Scroll Compressors are designed for Commercial/Industrial Applications and provide the same high quality and
efficiency as Reciprocating or Screw Compressors. They have been developed specifically for use in Packaged
Chillers and Condensing Unit products.
New enhanced condenser fins, plus modular construction provide for increased commonality of parts, high unit
electrical efficiency, and compact footprint throughout the line. This enables shorter lead times, while still offer-
ing all the optional features mounted, piped and wired to meet your exact needs. In fact, Dunham-Bush is famous
for its design flexibility. Our customers find that we can handle special applications that others might turn away.
ACDS-B units feature state-of-the-art full function, PC Windows® based, microcomputer controller standard on
all model sizes with an optional tie-in to a building management system. Remote monitoring via optional modem
allows instant diagnosis by the user or a Dunham-Bush technician.
Upon shipment, the new ACDS-B unit is installation-ready with its compact size, reduced weight, and complete
factory piping and wiring. Refrigerant charge is included and a thorough factory test under load is conducted on
each unit to insure trouble-free start-up operation.
